Robert Ludlum's The Ares Decision by Kyle Mills

Covert-One top operative Dr. Jon Smith and ex M-16 agent Peter Howell are sent to Africa on a mission to subdue a frenzied leader who is threatening the world with a fast-acting horrendous parasite. To make matters worse, the director of Iranian Intelligence is in Uganda trying to get this biological weapon to unleash it on the West. Pretty exciting, hate to think this might be possible.
